Abstract (en)
[origin: US5041216A] The fluidized bed reactor for biological treatment of effluent essentially comprises a container (1) over the base 2 of which elongated gassing units having gas exit apertures (5) are arranged parallel to one another, in such a way that in each case two neighboring circulating currents (8, 9) in mirror-image symmetry are produced in the reactor. In addition, the reactor (1) is supplied with a retention system (16) arranged on the outside for the separation of carrier particles for biocatalysts suspended in the effluent.
Abstract (de)
Der Wirbelbettreaktor zur biologischen Abwasserreinigung besteht im wesentlichen aus einem Behälter (1),über dessen Boden 2 langgestreckte Begasungseinheiten (3,4) mit Gasaustrittsöffnungen (5) parallel zueinander derart angeordnet sind, daß im Reaktor jeweils zwei benachbarte, spiegelsymmetrische Umlaufströmungen (8,9) erzeugt werden. Außerdem ist der Reaktor (1) mit einem außerhalb angeordneten Rückhaltesystem (16) zur Abscheidung von im Abwasser suspendierten Trägerpartikeln für Biokatalysatoren ausgestattet.
